March 8th marks twenty years since the release of Soundgarden’s critically-acclaimed 1994 album, Superunknown.

Both a critical, and commercial success, Superunknown continued a departure from the band’s earlier releases, and as such, earned the US rock group multiple Grammy Awards, helping to redefine alternative rock and paid a pivotal influence to future rock.

In celebration of the anniversary, Soundgarden are set to reissue the LP in two deluxe versions as of 2nd June. The first, ‘The Deluxe Edition’ is a 2-CD package featuring the remastered album along with disc two consisting of demos, rehearsals, B-sides and more. Meanwhile, ‘The Super Deluxe Edition’ is a 5-CD package featuring the remastered album, additional demos, rehearsals and B-sides alongside the full album mixed in Blu-ray Audio 5.1 Surround Sound.

Additionally, the ‘Super Deluxe Edition’ will be packaged in a hardbound book with a lenticular cover, liner notes by David Fricke and newly reimagined album artwork designed by Josh Graham. It also features never-before-seen band photography by Kevin Westerberg. A 2-LP gatefold of the original 16 vinyl tracks remastered on 180-gram vinyl in a gatefold jacket will also be made available. In addition, the Superunknown singles and associated b-sides with newly interpreted artwork sleeves by Josh Graham will be reissued on Record Store Day, April 19th, as a set of five limited edition 10″ vinyl records.
